Hi there,

I have a 3rd party warranty (my mistake for going with them) on my W205 that doesn't cover light assemblies as it states in excluded section "We do not cover lamp assemblies or bulbs, including headlamp self leveling and igniter systems."

My day time running light has gone out and I went for diagnostics from independent Mercedes specialist and it turns out to be faulty "light control module".

My warranty has rejected the claim saying that it is part of headlamp assemblies.

what would you say is it part of assembly or light control module is a separate module that interfaces with the assembly to control the lighting functions because light assembly contains the physical components like the housing, lenses, and bulbs?

The women I spoke to on phone only said "I rejected the claim because I know it is part of assembly" when I asked for written confirmation of claim rejection I have not received anything.

How should I proceed?

Can anyone provide any technical specification of document for this model that states otherwise?

Thank you

 

It sounds like it could be a bad/faulty Control Module that sits behind the headlight. You can access it through the wheel well, remove 3 torx T20 Screws and disconnect the cable that connects to the board. Then entire module can be taken out at that point. You can visually inspect the board to see if there are any burnt components or use a DMM to verify for shorts, etc.

If you have a working DRL, try using that board in the bad DRL to verify.
